Abstract:	Preparation has been carried out Ni-N-TiO2 thin film nano-sized , which is attached to the glass substrate. Preparation of thin layers (films)oN-TiO2 done by dip coating into the sol-gel prepared by reflux and then calcined at 450 C. The film characterization is with DRS, XRD, FTIR, SEM, BET, and potentiostat. DRS measurement results indicate wavelength in the visible region, XRD measurements showed that the resulting film is dominated by the Ni-N - TiO2 in the anatase form and has a size of 15.56 nm crystallite size. While the results of the FTIR Characterization indicates Ti-O, -NO and Ti-N bond. Meanwhile SEM measurements show that small crystal size. Pore surface area2of composite Ni-N-TiO2 from the result of measurement has a surface area of 92.79 m /g Photoelectrochemical test with potentiostat, by placing the film Ni-N-TiO2/Ti as the working electrode and the Nirrent response of light to produce Ni-N-TiO2/Ti. This system can be developed into a useful sensor for determining COD in a way that has never existed before.
